Profar, regarded as the consensus No. 1 prospect in baseball entering the 2013 season, missed all of last season with shoulder problems after hitting .234/.308/.336 in 85 games as a rookie in 2013.

Profar originally hurt his shoulder last spring training. A Dallas Morning News report in December said Profar had rejected the idea of a surgery at that time, saying "I already missed one season. I don't want to miss another."

It's a devastating blow for Profar. While he's still very young -- he turns 22 tomorrow -- losing two full years of development time at such a crucial age is obviously detrimental to his growth as a player. I can't recall a position player losing two entire seasons with the same injury.

The Rangers still have Elvis Andrus and Rougned Odor up the middle. Odor was rushed to the majors last year with all the injuries but held his own as a 20-year-old rookie, hitting .259/.297/.402.
